T-Mobile Says Its 1900MHz UMTS Covers 142M People

YMMV

Of course, having a few towers lit up is not the same as good coverage. I've been carrying an iPhone on T-Mobile for much of the past two months in Philly and New York, and while basic coverage has been great, 3G coverage has been 50%, at best.

Yes same with me and my unlocked Note 2 from ATT. In the city area I am experiencing about 50% for 3G and Edge when I am driving. However I am so lucky to have 4G where I live, at school, and at work where I spend about 80% of my time. So I am very fortunate in that sense. The 4G speeds are beast! Ranging from 2Mbps up to 10mbps they are even faster then my cable internet Time warner call them Time Failure haha.
